ROLLER-BEARING.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed June 13, 1908. Serial No. 438,270.

1b all whom 'it may concern.'

Be it known that I, ONESIME E. MICHAUD, a citizcnfof the United States, and a resident of the city of St. Louis and State oi Missouri, have invented a new and useful Improvenient in Roller-Bearings, of which the following is a specification.

This invention relates to roller bearings and has for its principal objects to secure a true rolling contact of the rollers, to provide for the spacing of the rollers, to rovide for the ready removal and renewa of the parts, and to attain certain advantages hereinafter more fully appearing.

This invention consists in the parts and in the arrangen'ients and combinations ol' parts hereinafter described and claimed.

In the accompanying drawings which form part of this specification and wherein like symbols refer to like parts wherever they occur, Figure l is a longitudinal section through a wheel hub shovvingfrller bearings embodying my invention applied thereto; Fig. 2 is an enlarged fragmentary 'z5/sectional view on the line 2f-2 of Fig. l;

Fig. 3 is an enlarged sectional view on the line 3 3 of Fig. l, portions being broken away; Fig. 4 is a side elevation of a bearing rincf; Fin". 5 is an edge view of one of the loclinfr devices; Fig. 6 is a front elevation of saidalocking device; Fig. 7 is a longitudinal section of a ortion of a wheel hub embodying a modllication of my invention; Fig. 8 1s a longitudinal section of the bearing ring shown in Fig. 7; Fig. 9 is a cross section on the line 9-9 of F i0. 7; and Fig. 1() is a. detail View of one of the locking devices shown in Fig. 7

The rollers in some roller bearings are arranged in a circular series and they are s aced apart by special cages or rings provided for the purpose. Usuall these cages comprise a pair of rings rigi ly connected With cross members, or the several rollers have pintles at their ends which are journaled loosely in perforations in said rings, in Which case the ends of said pintles are upset or headed on the outside of the rings. In such constructions, it is troublesome to remove parts to make re airs, and es ecially should only a single ro ler become roken. By my invention the parts may be quickly removed and the damaged part or parts renewed without the use of special tools or returning the bearing to the factory as is necessary with most bearings now in use.

I The main elements of my bearing are a groovcd bearing ring, a series of rollers having end pintles journaled loosely in spacing rings, and separable or detachable locking devices adapted to secure said spacing rings in proper relation to said rollers.

Referring to the first sheet of drawings, the bearing therein illustrated comprises a bearing ring l which is sleeved on the axle member A. This ring is provided with an annular groove 2 in which the rollers 3 are adapted to run. Preferably, the sides of the groove are inclined or outwardly fiared to corres ond to the beveled end portions of the ro 1ers. The rollers 3 are provided at their ends with pintles or trunnions 4 which are loosely ournaled in perforations in spacing rings 5. These spacing rings fit loosely around shouldered portions 6 on the bearing ring l at each side of the grooved portion 2. AdJoining the shouldered portions 6 are pe ripheral grooves 7. In these grooves are placed the locking devices. In this modification the locking device comprises a sectional ring and filler piece. The ring comprises a semicircular portion 8 of a Width and diameter to t the groovcd portion 7 of the bearin ring. Hinged to the rstdnentioned semicircular portion S is a semicircular securing portion or bail 9. The interior diameter of the bail 9 is greater than that of the portion 8 or sufficient to clear the peripheral flaned portion l() formed at the edge of the caring ring by the groove 7. The space between the bottom of the groove 7 and bail 9 of the locking member is filled in with a flan ed segmental filler piece or member 1l, which is the counterpart of the main portion 8 of the ring.

In assembling the parts of the bearin the rollers are placed in the groove 2. hey may be temporarily held in place by a circular spring clip or any suitable device. rlhe spacing rin s 5 are then placed in position, after Whic the hinged locking rings are placed in position. In applying the locking device the bail or portion 9 1s turned at ri ht angles to the portion 8 which may then e laced in the groove 7. Then the segmenta filler piece 11 is placed 1n the roove op osite from portion 8 and the inged loc ing portion 1s moved over said filler piece.

In the drawin my invention is applied to the hub B o a vehicle wheel. In this case, the hub is provided with two bearing cups l2 Whieh are connected by a tubular sleeve 13 extending through the hub. ln eaeh ot the eup portions is titted one ot' m v hearings. 'lhe inner bearing cup 12 is provided with a hardened bushing or bearing ring 'i4 upon which the rollers l far, while the outer eup itself eonstitutes the bearing ring. The axle A is provided with a eollar or shoulder 1Q' nd a tianged nut lo whirh serve to hold L bearings in place.

1n the second sheet of drawings` l have illustrated ay modification of the roller bearing. ln this ease the rollers are adapted to bear directly against the axle and the bea ring ring la is adapted to be fitted in tht` eup 1Q at the end of the hub. This ringl 1u is provided with an internal groove in whieh the rollers 3 fit. The spacing rings 5 are similar to those hereinbefore deseribed and fit loosely Within the shouldered portions 1T in the bearing ring la. The looking deviee in this ease comprises a flanged ring 1R, which is adapted to fit the portion 19 oi' said bearing ring. A resilient securing member 2t) is provided having diametrieallv extend ing projections 21 adapted to fit in registering openings in the looking ring and bearing ring.

Obviously, any ordinary my bearing is applieable to shaft as Well as to vehieles and may be modified without departing from my invention. Therefore, l do not Wish to be limited to the eonstruetions and arrangements shown.

that I claim is:

1. A roller bearing comprising a bearing ring having an annular groove therein. annular shouldered portions at eaeh side of said groove, and annular recessed portions nextto said shouldered portions at the outer sides thereof, a series of rollers arranged to travel in the annular groove in said bearing ring, said rollers having axial end spindles, separable rigid spacing rings for said rollers, said spacing rings being adapted to looselT fit said annular shouldered portions and having a series of perforations arranged to receive the end spindles of said rollers, and annular retaining devices for said spaeing rinus detaehably secured in said annular recessed portions of said bearing ring.

L. A roller bearing eomprising a bearing ring,rollers arranged loeooperate therewith, separable sparing rings `tor said rollers, and lorlting deviees arranjred to hold said spaeing rings in plaee, said locking devices oomprising txvo semieireular members and a hail hinged to one ol' said members and adapted to ei'igage the other member.

Si. A roller bearing comprising an annular grooved bearing ring, rollers arranged to travel in said groove,separable spaeing rings x Yfor said rollers, and separable looking de vlees adapted to hold said spacing lrings 1n place, said looking deviees comprising two (counterpart semieirenlar members and a` bail hinged to one of said members and adapted to secure the other member thereto.

l. roller hearing eonnnising a bearing ring having an annularbearing groove. rollers arranged to travel in said groove, sepv arable spaeing rings for said rollers, devices for locking said spacing rings in place, said l sai-mg ring having annular grooves adjaeent to the respertive spacing rings, and each of said looking devices comprising two counterpart semieireular members adapted to tit iu one oi said grooves and one of said members having a bail arranged to seeure the other member thereto.

5. A roller bearing comprising an annula rly grooved bearing ring, rollers arranged to travel in said groove, separable spacing rings for said rollers` and separable securing rings for said spaemg rings,eaeh comprising a semi-Circular portion adapted to tit au annular groove in said hearing ring adjarent to its respective spacing ring, a semi circular portion of larger interior diameter hingedlv eonneeted to said first-mentioned portion, and a sepa able segmental filler pieee adapted to fit said groove in said bearing ringl beneath said last mentioned semi eireular portion.

ln testimony whereof l have signed my name to this specification in the presence oi' two subscribing witnesses this 11th day of June, 1909, at St. Louis, Missouri.
